TDK Offers High Current and Low DC Resistance Power Inductors for Automotive Power Circuits, Supporting Temperatures up to 150°C

DK Corporation has released a new VLS5030EX-D type inductor (5.3 x 5.0 x 3.0 mm (L x W x H)) as a part of the VLS-EX-D series of wire wound ferrite power inductors for automotive power circuits. part. These small components have excellent DC superposition characteristics and guaranteed performance at operating temperatures up to 150°C. The inductor is suitable for headlights, airbags, electric power steering (EPS), advanced driver assistance systems (ADAS), engine control units (ECU), and various other power circuit applications

Compared with TDK's standard VLS-EX-H series, the new VLS-EX-D series inductors have a higher rated current. These improvements are all thanks to the use of TDK's innovative metallic magnetic materials for the magnetic shielding function. Specifically for the VLS5030EX-D inductor, the rated Isat is 3.3 A at 4.7 μH, an increase of about 6% compared to a standard component of the same size 5.3 x 5.0 x 3.0 mm (L x W x H). In addition, thanks to the soldering method that connects the wound wires to the external electrodes, high reliability is achieved when used in reflow and high-temperature environments.

• Inductors for automotive power circuits have a high magnetic shield structure enabling high-density mounting

• Using TDK's metal magnetic material for magnetic shielding function, optimizing the ferrite core, thereby increasing the current and reducing the DC resistance

• Supports an operating temperature range of -40 to +150°C (including self-heating)

• AEC-Q200 and RoHS Compliant
